Why people hated Skyward Sword?

[Pavolink]

I liked, but more because it fixes some problems than being marvelous.

- Better rupee system. At least there's worth stuff to spend.
- A lite-RPG system upgrade. I'll like them to go in-deep for the next game.
- Enemies do more damage, althought the AI of most of them is focused on blocking "attacks", than"attacking" itself.
- Boss battles are better, Ghirahim battles have great AI.

But...

- Fi has a lot to say. Just make the next one without a companion or something like Navi-Midna.
- The Imprisioned battles were boring.

I'd prefer if Skyward Sword keeps as a standalone entry in the series, than being the way to go for future ones.
